backzone Africa/Lubumbashi
by Alois Treindl Feb. 28, 2022

Feb. 28, 2022

In file backzone there is an entry for Africa/Lubumbashi # Democratic Republic of the Congo (east) Zone Africa/Lubumbashi 1:49:52 - LMT 1897 Nov 9 2:00 - CAT There are scarce sources for time zones of former Belgian Congo. My main source for its time zone history is Henri le Corre, Régimes horaires pour l'Europe et l'Afrique. He has for the eastern provinces of Zaire GMT + 1 between 1897 Nov 9 GMT + 2 since 1920 Apr 25. Shanks follows le Corre. As does Francoise Schneider Gauquelin in he book Problèmes de l'heure resolus pout le monde entier. I think this is sufficient reason to change the zone into Zone Africa/Lubumbashi 1:49:52 - LMT 1897 Nov 9 1:00 - WAT 1920 Apr 25 2:00 - CAT For the province of Kisangani, formerly Stanleyville, le Corre gives a transition from GMT +1 to GMT + 2 on 1935 Jun 14. But as this agrees with Lubumbashi after 1970, I do not expect the creation of another backzone entry for that. This task will be left for my private pre-1970 TZ extensions.

proposed change to Europe/Kaliningrad in 1945
by Alois Treindl Feb. 21, 2022

Feb. 21, 2022

Currently the zone Europe/Kaliningrad has Zone Europe/Kaliningrad 1:22:00 - LMT 1893 Apr 1:00 C-Eur CE%sT 1945 Apr 10 2:00 Poland EE%sT 1946 Apr 7 3:00 Russia MSK/MSD 1989 Mar 26 2:00s 2:00 Russia EE%sT 2011 Mar 27 2:00s 3:00 - +03 2014 Oct 26 2:00s 2:00 - EET I wonder on which source this line is based: 2:00 Poland EE%sT 1946 Apr 7 It implies these time changes: 29 April 1945 from 2:00 to 3:00 like Poland DST 1 November 1945 from 3:00 back to 2:00 Russia took control of Königsberg/Kaliningrad in East Prussia on 10 April 1045. As a general rule, Russia imposed timezone 2:00 on occupied German territory in 1945, which is the same as German DST already in force from 2 April 1945. On 24 May 1945 Russia imposed double DST, making the effective time 3:00 east, until 24 Sept 1945, when it went back to 2:00 and then back to 1:00 (CET) on 18 Nov 1945. Now what happened in Königsberg? The Potsdam agreement of 2 August 1945 : (quote from Wikipedia) > The Conference has agreed in principle to the proposal of the Soviet > Government concerning the ultimate transfer to the Soviet Union of the > City of Koenigsberg and the area adjacent to it as described above > subject to expert examination of the actual frontier. Russia annexed the area on 17 October 1945, and integrated into the republic of Russia on 7 April 1946. Poland had no role to play in this matter. Regarding time regime, I would assume that the transition from 2:00 to 1:00 of 18 Nov 1945, for occupied Germany, did not happen in Kaliningrad. It was already annexed. It remained at 2:00 until 7 April 1946, when it was integrated and went to Moscow time. This transition on 7 April 1946 is also found in Shanks. Shanks does not have the double DST from 24 May to 24 September 1945, but I think he is wrong there. Why should the Russians have treated East Prussia from the rest of the occupied German territory in May 1945. That would make the zone table like this ( I marked the difference in red) Zone Europe/Russia/Kaliningrad 1:22:00 - LMT 1893 Apr 1:00 C-Eur CE%sT 1945 Apr 10 1:00 1:00 CEST 1945 May 24 2:00 1:00 2:00 CEMT 1945 Sep 24 3:00 1:00 1:00 CEST 1945 Oct 17 2:00 - EET 1946 Apr 7 3:00 Russia MSK/MSD 1989 Mar 26 2:00s 2:00 Russia EE%sT 2011 Mar 27 2:00s 3:00 - +03 2014 Oct 26 2:00s 2:00 - EET I have tried to simplify Zone Europe/Russia/Kaliningrad 1:22:00 - LMT 1893 Apr 1:00 C-Eur CE%sT 1945 Apr 10 1:00 SovietZone CE%sT 1945 Oct 17 2:00 - EET 1946 Apr 7 3:00 Russia MSK/MSD 1989 Mar 26 2:00s 2:00 Russia EE%sT 2011 Mar 27 2:00s 3:00 - +03 2014 Oct 26 2:00s 2:00 - EET but get an error: can't determine time zone abbreviation to use just after until time at this line in tzdata.zi 1 So CE%sT 1945 O 17 This is why I made the changes implied by rule SovietZone explicit

Maryland permanent DST
by Arthur David Olson Feb. 21, 2022

Feb. 21, 2022

A permanent-DST bill has been approved by the Maryland House of Delegates on a third-and-final 108-24 vote; it now goes to the state senate. Text of the bill is available at... https://mgaleg.maryland.gov/2022RS/bills/hb/hb0126T.pdf …and status of the bill at... https://mgaleg.maryland.gov/mgawebsite/Legislation/Details/hb0126 There are contigencies: (1) enacting of a similar act by Delaware, the District of Columbia, Pennsylvania, Virginia, and West Virginia; and (2) 15 U.S.C. § 260a being amended to allow the states or a state, individually, to observe a year–round standard time that is consistent with Eastern Daylight Time Alas, if the contingencies are met there may be short lead time before a change: Section 1 of this Act shall take effect on the earlier of the second Sunday of March or the first Sunday of November after the [contigencies have been met]… Alas further, the senate (unlike the house) has returned to in-person hearings; written communications can be sent. One suggestion I’ve thought of making is to change “the earlier of” to “the later of” for kick-in; that would buy at least a few guaranteed months of lead time. I’d welcome any better suggestions; I’d also welcome any Marylander with more political weight than I have (read: anyone) to weigh in. --ado

Issues about parts of Europe/Moscow in 1981/1982
by Alois Treindl Feb. 21, 2022

Feb. 21, 2022

I have the impression that some of the comments in the Russia section in file 'europe' have not been followed through in the actual zone tables. I refer to the lines beginning here # From Stepan Golosunov (2016-03-07): # 11. Regions-violators, 1981-1982. # Wikipedia refers to # http://maps.monetonos.ru/maps/raznoe/Old_Maps/Old_Maps/Articles/022/3_1981.… # http://besp.narod.ru/nauka_1981_3.htm ... until # 12. Udmurtia Also the Russian wikipedia page https://ru.wikipedia.org/wiki/%D0%9C%D0%BE%D1%81%D0%BA%D0%BE%D0%B2%D1%81%D0… contains the sentence (in Google translation) > In the autumn of 1981, Arkhangelsk, Vologda, Yaroslavl, Ivanovo, > Vladimir, Ryazan, Lipetsk, Voronezh, Rostov-on-Don, Krasnodar and > regions to the east of those named (about 30 in total) parted ways > with Moscow time.However, the convenience of common time with Moscow > turned out to be decisive - in 1982, these regions again switched to > Moscow time. Shanks International atlas has similar information, and also the Russian book Zaitsev A., Kutalev D. A new astrologer's reference book. Coordinates of cities and time corrections, - The World of Urania, 2012 Russian: Зайцев А., Куталёв Д., Новый справочник астролога. Координаты городов и временные поправки To me it seems that an extra zone is needed, which starts with LMT util 1919, later follows Moscow since 1930, but deviates from it between 1 October 1981 until 1 April 1982. I suggest to call this zone Europe/Yaroslavl, because Yaroslavl with a population of 608'000 seems to be largest city in the deviating area.
